Abstract
Two experimental studies are reported that were intended to evaluate alternative man-computer communication techniques within the context of a computer-based image interpretation facility. The first experiment, comparing five different data entry procedures, indicated that, although a procedure requiring the interpreter to enter report data directly using a teletype keyboard resulted in the shortest overall throughput time, a procedure involving message composition by the image interpreter with subsequent transcription by a communicator minimizes the time spent by the interpreter in report generation and maximizes the time available for the detection and identification of targets on aerial imagery. The second experiment evaluating alternative word form-data entry format combinations, showed no differences among the six combinations studied.
